Next comes the temperature entry test which will indicate the current temperature detected by the probe on the display. To exit Test
Mode, switch off the machine.
4 PRODUCTION TEST MODE
This mode is activated by switching on the machine with the H key held down. In this mode, pressing the A key in succession will
allow individual outlets to be switched on and off. The outlet codes will be indicated on the display. Once the activation of the outlets
is complete, the temperature detected will be displayed. To exit the test, switch off the machine.
5 PROTECTION AGAINST EXCESSIVE DENSITY
In the case of excessive product density, in order to avoid damage to the dispenser, both the freezer and the mixer will be stopped
for three minutes and one of the following messages will appear on the display: "AL03", "AL06" or "AL08". After three minutes, both
mixing and freezing will be reactivated and the previous density setting will be decreased by one level.
To reset the alarm message and return to the fixed display, hold down the B key for three seconds.
